Comment OLPC XO-1 (Score 1, Interesting) 167
I bought my xo for exactly the type of thing that you are asking about. It's display is really well suited for reading ebooks, it's sunlight readable and 200dpi. I get around 5 - 6 hours of reading time when I turn everything off and put the display into low power(ebook) mode. The processor in it isn't the beefiest a 433mhz amd geode, but you can browse the web with it. I think they usually go for ~$200 on ebay.
